Parameters
- pSrc
- Pointer to the source image ROI.
- srcStep
- Distance, in bytes, between the starting points of consecutive lines in the source image.
- pDst
- Pointer to the destination image ROI.
- dstStep
- Distance, in bytes, between the starting points of consecutive lines in the destination image.
- dstRoiSize
- Size of the source and destination ROI, in pixels.
- maskSize
- Size of the filter kernel.
- borderType
- Type of border. Possible values are:
- ippBorderConst
- Values of all border pixels are set to a constant.
- ippBorderRepl
- Border is replicated from the edge pixels.
- ippBorderInMem
- Border is obtained from the source image pixels in memory.
Mixed borders are also supported. They can be obtained by the bitwise operationORbetween any of theippBorderRepl,ippBorderConst, orippBorderMirrorvalues and theippBorderInMemTop,ippBorderInMemBottom,ippBorderInMemLeft,ippBorderInMemRightvalues. - borderValue
- Constant value to assign to pixels of the constant border. This parameter is applicable only to theippBorderConstborder type.
- pBorderValue[3],pBorderValue[4]
- Pointer to constant values to assign to pixels of the constant border. This parameter is applicable only to theippBorderConstborder type.
- pBuffer
- Pointer to the work buffer.
Description
Before using the
ippiFilterMaxBorder
and
ippiFilterMinBorder
functions, you need to compute the size of the work buffer
pBuffer
using the
ippiFilterMaxBorderGetBufferSize
or
ippiFilterMinBorderGetBufferSize
functions, respectively.
These functions operate with ROI (see
Regions of Interest in Intel IPP
).
The
ippiFilterMaxBorder
and
ippiFilterMinBorder
functions apply the maximum/minimum filters, respectively, to the source image ROI. The size of the source image ROI is equal to the destination image ROI size
dstRoiSize
. The values of border pixels are assigned in accordance with the
borderType
and
borderValue
parameters. The kernel size of the filter is arbitrary and depends on the
mask
value.
The anchor cell is the center cell of the kernel, highlighted in red. The anchor cell is defined as:
x
=(
maskSize.width
- 1)/2
y
=(
maskSize.height
- 1)/2
where
(
x
,
y
) are cell coordinates.
Return Values
- ippStsNoErr
- Indicates no error.
- ippStsNullPtrErr
- Indicates an error when one of the specified pointers isNULL.
- ippStsSizeErr
- Indicates an error whendstRoiSizeis negative, or equal to zero.
- ippStsBorderErr
- Indicates an error whenmaskis less than, or equal to zero.
- ippStsBorderErr
- Indicates an error whenborderTypehas an illegal value.
